Question Set: Classification of Life
  1. Why do scientists classify organisms?
     
  2. What could happen to the exchange of scientific information if organisms were not classified?
     
  3. List the rules to follow for writing scientific names of organisms.
     
  4. What are the rules of nomenclature?
     
  5. What is the value of using a universal system of classification?
     
  6. What are the drawbacks of the Linnaean system?
     
  7. Examine the relationship between animals and cyanobacteria on the phylogenetic tree of life (Fig. 1.16). What does the distance between the two suggest about their evolutionary history?

<p><strong>Fig. 1.16.</strong> This phylogenetic tree of life shows the three domains, which make up all of life on Earth. The length of the branches on phylogenetic trees represents evolutionary time.</p>
